The equation that shows one way that a plant cell stores energy in an energy-carrier molecule is this: NADPH -> NADP+ + H+
How the plant cells store energy
The equation, NADPH → NADP+ + H+ is found in the Calvin cycle. This pathway is responsible for converting carbon dioxide into organic molecules like glucose.
During the light-dependent reactions, energy is captured from sunlight and stored in ATP (adenosine triphosphate) and NADPH. During the light-independent reactions the energy and reducing power from ATP and NADPH are used to fix carbon dioxide and build organic molecules.
